I had the same issue. I think this IS a bug in TurboTax - When you're entering the 1099-INT, it asks 'Do any of these uncommon situations apply?' TurboTax shouldn't list New Hampshire in the drop down for 'My state doesn't tax all of this interest'. NH is still taxing dividends & interest in 2024 - this is being phased out and will go away for 2025 taxes. I changed my answer to 'None of these apply' - and the amounts transferred correctly to the NH DP-10 form.
